Error: prefix not set

[Yves Blusseau]

Hi all,

I see a message "prefix not set" when the grub kernel try to load the 
grub.cfg file and that the normal module is already include in core.img.
I explain: the "normal" module is include in core.img by grub-mkimage 
because i add the "ls" module as module to add in core.img. When i start 
my PC the grub kernel is load normaly but when it switch to normal mode 
the error "prefix not set" is displayed on the screen. I have check and 
the prefix is good in the rescue shell and in normal mode. This message 
is only display if the normal module is include in core.img
